Angry Blower motor inop on 99 tj

during this last winter, I turned hard right into my driveway while running the heater. When I came out a while later, I noticed the blower motor wasn't working. I turned everything off, drove around and the next time I started the vehicle the motor worked. This happened two or three times over a two month period.
Fast forward to 3 weeks ago and after making a hard right uturn, the blower motor quit. It is still inop.
I've read some threads and inspected all of the plugs at the console control, all fuses, the resistor and the motor itself, now removed. I hooked the motor (using jumper cables and alligator clips) to the jeeps battery. NO results. Not a hum, or click, or sputter, or spark, nothing.
Got out my multi-meter and checked the curcuit as the instructions directed.
*note* me and electricity don't do well. I know just enough to get into trouble. So I follow the instructions and get a reading on my craftsman meter of approx 1940-1970.
When set to any of the other resistor settings it gives o as a reading. The instructions said that at the initial test setting,(which had a symbol that looks like a ground), it said an audio alarm will sound if the reading goes below 20 ohms. So is a reading of over 1900 a good reading?
